Yeah if you're purely after vocal crit it goes in here. Covers are more about the song and the recording itself.

As for the voice, sounds cool man. I like it. What you're doing there suits the sort of vulnerable, acoustic vibe of the song. Depends on where you want to be with your voice though. There's a slight shakiness in your voice and at times you descend into an almost speaking voice, but if that's just your style then there's nothing wrong with that. People love vocal flaws.
